The United Nations said in a report released Thursday the “scales have tipped” for the first time in the fight against AIDS, with more than half of people infected with HIV now on drugs to treat the virus.

According to the report, about 19.5 million of the 36.5 million people who are HIV-positive were taking AIDS drugs in 2016, compared to 17.1 million the previous year.

“We met the 2015 target of 15 million people on treatment and we are on track to double that number to 30 million and meet the 2020 target,” said Michel Sidibe, Executive Director of UNAIDS. “We will continue to scale up to reach everyone in need and honor our commitment of leaving no one behind.”
